Researchers from Osaka University have identified a protein complex crucial for male fertility, revealing the TEX38/ZDHHC19 interaction regulates sperm development and structure. The study found that disrupting this complex can cause sperm deformity and infertility, providing insight into the causes of male infertility.
A research team led by Osaka University has identified a new mechanism crucial for the initiation of autophagy, a self-degradation process cells use to eliminate unneeded or damaged components. The palmitoylation of ULK1 by ZDHHC13 plays a critical role in this process.
A new study found that 2-bromopalmitate treatment reverses cell senescence in human vascular smooth muscle cells, reducing DNA damage markers and promoting cell proliferation. The research suggests a critical role for protein palmitoylation in regulating the senescent phenotype.
Scientists at the University of Illinois Chicago have found a way to selectively degrade disease-causing proteins in specific parts of cells. By studying the movement of enzymes inside cells, they discovered that attaching or detaching a fat molecule can direct where these enzymes go.
Researchers at WashU Medicine discovered a link between obesity and diabetes, highlighting the importance of an enzyme in fatty acid processing. The study suggests that defects in this enzyme contribute to insulin hypersecretion and beta cell failure, paving the way for potential therapeutic interventions.
Researchers have discovered that palmitoylation can occur at the plasma membrane, paving the way for innovative drug discovery strategies. A novel tool, SwissKASH, allows for dynamic observation of this process, enabling precise targeting of oncogenic proteins in cancer therapy.
Scientists have identified two small-molecule compounds that specifically target the STING protein, which plays a key role in triggering an immune response. These compounds effectively blocked STING-mediated cellular activation and demonstrated therapeutic potential in mouse models of autoinflammatory disease.
Researchers used proteomics to understand the pathogenic mechanisms of Trichomonas vaginalis and Aspergillus fumigatus, identifying palmitoylation sites in T. vaginalis proteins that regulate infectivity and a strategy for A. fumigatus to evade macrophage destruction. This work suggests potential treatments for these infections.
Researchers from Boston University School of Medicine discovered that enhancing palmitoylation in the variant MC1R protein of redheads can reduce cancer risk for melanoma. This finding offers a potential alternative strategy to prevention by reducing sun exposure, which has been the focus of public health work.
A Japanese research group discovered that two types of palmitoylating enzymes regulate synaptic protein PSD-95 in different ways, contributing to stable synaptic activity. This finding suggests individual enzymes have distinct functions and may represent therapeutic targets for neurological disorders.
